UNITED STATES PATENT OFFICE.

GAS BURNER. I

Application filed June 11, 1925. Serial No. 36,400.

To all whom it may concern:

Be itknown that I, AUoUs'rUs F. THOMP- soN, a citizen of the UnitedStates of America, and a resident of Huntington, county of Cabell, andState of West Virginia, have invented certain new and usefulImprovements inGas Burners, of which the following is a full and clearspecification.

This invention relates to that type of Bun .10 sen gas-burner in whichthe gas is distributed along a series of burners and injected into eachof the burners through a perforation in the pipe, the-burners being, soarranged that the jetof gas dra s in the necessary supply of air,

after set forth.

In the drawing Fig. 1 is a side elevation, partly in sec tion, showingthe essential parts of the I W burner;

v Fig. 2 is a plan view thereof, partly broken away;

Fig. 3 is a vertical sectional view. 4 In the drawing annexed, 5designates the gas-supply pipe provided along its top with a series ofperforations 6f spaced to inject a jet of gas into uprighttubes 7 whichare, at their upper ends, adapted to be connected to any suitableburner-tips or mixin -chamhers or used as shown, as a multiple unsenburner. s v

The tubes 7 are mounted in a metal bar 8 supported parallel with thesupply-tube 5. The support for this tube consists of. a pair ofgoose-necks 9 formed on the ends of the supporting-bar t5 and providedwith holes through which the gas-supply tube 5 passes. Each goose-neckis formed by bending down the end of the supporting-bar and then curvingit upwardly, the holes for the gas-pipe as more fully hereinbeingprovided in the vertical portions of the goose-neck. This arrangementaffords a broad substantial bearing for the gaspipe and also provides asupport for a set-screw 1O tapped through the curved part of thegoose-neck andhaving its upper end bearing against the gas-pipe, to thuslock the gas-pipe removably in position. .This reinovability of thegas-pipe is desirous because of the need for pipes having varioussizedjet-openings 6; this makes the gaspipes interchangeable, enabling me toinsert any capacity gas-pipe that may be necessary for the particularburner I am assembling. 7

As is obvious, air is drawn -into each of the burner-tubes 7 by the jetof gas issuing from the gas-pipe, and the gas and air are mixed in thetube and also in the usual mixing-chan ber attached to the upper ends ofthe tubes. To prevent back-firing, I constrict each tube 7 near its.base by providing an annular head 11 therein. Some or all of thesebeads may be provided with perforations 12-to drawrnore air into thetubes by the suction created by the upgoing jet, when desired on hertainquality of gas. a

What I claim as new is: A gas-burner of the type herein disclosedembodying a bar supporting a plurality of burner-tubes and having eachof its ends bent upon itself to form a U-shaped member, the two legs ofeach of these members being provided with corresponding holes, a supply-pipe extending through said holes, and

set-screws for removably holding the gaspipe in said U-shaped members.

In testimony whereof I hereunto afiir; my signature.

AUGUSTUS FRANKLIN THOMPSON.
